Uyazi ukuba amathumbu ethu enza umsebenzi ongakanani ukuze atye kakuhle ukutya esikutyayo aze afunxe izondlo ezisinika imizimba yethu? Kufana nomzi-mveliso. Ngoko ke, ukuze senze lo msebenzi ngokufanelekileyo, amathumbu ethu adinga ukunikezelwa kwegazi elicocekileyo, elineoksijini, nelityebileyo kwizakhamzimba. Namhlanje, siza kuthetha ngomnye wemithambo yegazi ephambili ebonelela ngokunikezelwa kwegazi okuxabisekileyo. Kwizonyango, siwubiza ngokuba yiSuperior Mesenteric Artery . Nangona eli gama linzima kancinci, umsebenzi ulula kakhulu. Makhe sibone ukuba yintoni le.
Ngamafutshane, yintoni i-Superior Mesenteric Artery?
Lo ngumthambo obalulekileyo ophuma ngqo kumthambo wegazi oyintloko nowona mkhulu emzimbeni wethu, i-aorta . Khawuthelekelele ukuba umbhobho wamanzi omkhulu emzimbeni wethu yi-aorta. Ngoko ke lo mthambo we-mesenteric ongcono kakhulu ngumbhobho omncinci ophuma apho.
Igama elithi 'Superior' egameni layo lithetha 'ngaphezulu'. Oku kungenxa yokuba ikwindawo engaphezulu kweminye imithambo ehambisa igazi emathunjini. Kukwakho nomnye umthambo obizwa ngokuba yi-'Inferior Mesenteric Artery'. Uhambisa igazi kwiindawo ezisezantsi zamathumbu ethu amakhulu.
Ngoko ke umsebenzi oyintloko wale mithambo iphambili ye-mesenteric kukubonelela ngegazi elineoksijini nelinezondlo ezininzi kwindawo ephakathi yenkqubo yethu yokugaya ukutya, okuyipancreas, amathumbu amancinci, kunye namathumbu amakhulu. Olu nikezelo lwegazi lubalulekile ukuze la malungu asebenze kakuhle.
Iphi le mithambo yegazi? Ikhula njani?
Lo mthambo uphakathi kwenkqubo yethu yokugaya ukutya, esiswini sethu. Uqala kwi-aorta uze udlule emva kwepancreas yethu.
Amasebe amaninzi amancinci aphuma kulo mthambo uphambili, kanye njengamasebe aphuma kwisiqu somthi. Elinye la masebe linika igazi kwiindawo ezahlukeneyo zenkqubo yokugaya ukutya. Makhe sijonge ukuba la masebe aphambili ngawaphi na amalungu omzimba anika igazi kuwo.
| Igama lesebe lomthambo (iSebe leMithambo) | Amalungu/iindawo ezibonelela ngegazi |
|---|---|
| Umthambo we-pancreaticoduodenal ophantsi | Ukuya entlokweni yepancreas kunye ne-duodenum (inxalenye yokuqala yamathumbu amancinci) |
| Umthambo we-colic ophakathi | Ikholoni eguqukayo |
| Umthambo we-colic wasekunene | Inxalenye enyukayo yamathumbu amakhulu (ikholoni enyukayo) |
| Imithambo yeJejunal kunye neIleal | Inxalenye ephakathi neyokugqibela yamathumbu amancinci (iJejunum kunye neIleum) |
| Umthambo we-Ileocolic | I-appendix, inxalenye yokugqibela yamathumbu amancinci, kunye nenxalenye yokuqala yamathumbu amakhulu (i-cecum) |
Okukhethekileyo kukuba amasebe omthambo we-mesenteric ophambili kunye namasebe omthambo we-mesenteric ongaphantsi adibene. Cinga nje xa indlela ephambili ivaliwe, sithatha indlela esecaleni eyahlukileyo. Ngenxa yezi nxu lumano, nokuba umthambo omnye uvaliwe, igazi lisenokuthunyelwa emathunjini ukuya kwinqanaba elithile. Olu luyilo oluhle kakhulu lwendalo.
Zeziphi izifo ezichaphazela le mithambo yegazi?
Njengayo nayiphi na enye imithambo yegazi, umthambo we-mesenteric ophambili unokuchaphazeleka ziimeko ezithile zempilo. Kubalulekile ukuzazi ezi, kuba ngamanye amaxesha zinokuba yingozi.
| Imeko | Icacisiwe ngokulula |
|---|---|
| Ischemia yeMesenteric | Le yeyona ngxaki ixhaphakileyo. Iyenzeka xa i-cholesterol kunye namafutha eqokelelana ngaphakathi kwemithambo yegazi (i-atherosclerosis) okanye i-blood clot (i-thrombus) isenzeka.Ukuhamba kwegazi emathunjini kuyancipha okanye kuvaliwe ngokupheleleyo. Le yimeko enzima efuna unyango olungxamisekileyo. |
| I-Mesenteric Aneurysm | Okwenzekayo apha kukuba udonga lomthambo lubuthathaka kwaye luvuthuluka njengebhaluni. Oku kuyingozi kuba ngenye imini olu vuthuluka lungaqhuma lubangele ukopha okukhulu esiswini. |
| Isifo seNutcracker | Le yimeko engaqhelekanga. Njenge-nutcracker, umthambo wezintso wasekhohlo ubambeka phakathi kwe-mesenteric artery ephezulu kunye ne-aorta. Oku kuthintela ukuhamba kwegazi elihluziweyo ukusuka kwizintso ukuya entliziyweni. Oku kunokubangela iimpawu ezifana neentlungu zomqolo kunye negazi kumchamo. |
| Isifo seMithambo seMesenteric esiPhezulu | Le yimeko engaqhelekanga kakhulu. Kwimeko enjalo, inxalenye yokuqala yamathumbu amancinci (i-duodenum) inamathela phakathi kwe-mesenteric artery ephezulu kunye ne-aorta. Oku kuthintela ukutya ukuba kungadluli esiswini. Iimpawu ezifana nentlungu yesisu kunye nokuhlanza zinokwenzeka emva kokutya. |
Siyikhusela njani le mithambo ibalulekileyo?
Enyanisweni, ukugcina inkqubo yokujikeleza kwegazi emzimbeni wethu wonke, kungekuphela nje lo mthambo, isempilweni yeyona nto ibalulekileyo. Zimbalwa izinto ezilula onokuzenza ukuze wenze loo nto.
- Indlela elungileyo yokuzilolonga: Zilolonge ubuncinane iintsuku ezimbalwa ngeveki. Nokuba yinto efana nokuhamba, ukubaleka, okanye ukukhwela ibhayisekile ilungile.
- Ukutya okunempilo kwentliziyo: Nciphisa ukutya okunamafutha amaninzi, i-cholesterol, kunye netyuwa kangangoko unako. Yitya imifuno emininzi, iziqhamo, iimbotyi, kunye nokutya okunefayibha eninzi.
- Yeka ukutshaya ngokupheleleyo: Ukutshaya yeyona nto ibangela umonakalo omkhulu kwimithambo yegazi.
- Gcina ubunzima obusempilweni: Kubaluleke kakhulu ukugcina ubunzima obusempilweni obuhambelana nobude bakho. Ukuba utyebile kakhulu, zama ukunciphisa umzimba.
- Lawula ezinye izifo: Ukuba unezifo ezifana nesifo seswekile, i-cholesterol ephezulu, okanye uxinzelelo lwegazi oluphezulu , landela imiyalelo kagqirha wakho, usele amayeza akho ngokufanelekileyo, kwaye ulawule ezo meko kakuhle. Ezi zifo zingonakalisa imithambo yakho yegazi.
Ufanele uye nini kugqirha?
Ukuba unezinye zeempawu ezilandelayo, musa ukuzityeshela. Musa ukuchitha ixesha, bonana nogqirha wakho ngoko nangoko.
- Intlungu yesisu eqatha, ekhawulezileyo.
- Igazi elikwindle okanye igazi elikwimchamo.
- Ukunciphisa umzimba ngaphandle kwesizathu.
Iimpawu ezinje ngezi zinokuba luphawu lwenye yezi meko sizixubushileyo apha ngasentla, ngoko ke ukufuna unyango kwangethuba kunokunceda ukuthintela ezinye izifo ezinzulu.
Ukuqukumbela, umthambo we-mesenteric ophambili yinxalenye ebalulekileyo yokugcina inkqubo yethu yokugaya ukutya iphilile kwaye isebenza. Ukuba ukuhamba kwegazi kuthintelekile, kunokubakho iingxaki ezinkulu. Ke ngoko, sonke masiqaphele ukugcina yonke inkqubo yethu yokujikeleza kwegazi isempilweni ngokwamkela indlela yokuphila elungileyo.
Umyalezo Wokuya Ekhaya
- I-Superior Mesenteric Artery ngumthambo omkhulu othwala igazi elineoksijini nelinotyebi kwizakhamzimba ukuya kwizitho ezibalulekileyo ezifana namathumbu ethu kunye nepancreas.
- Ukuba amafutha okanye amahlwili egazi akhiwa ngaphakathi kolu thambo lwemithambo yegazi (i-mesenteric ischemia) , ukuhamba kwegazi emathunjini kunokunqanyulwa, nto leyo ebangela imeko embi kakhulu.
- Ungaze uzityeshele iimpawu ezifana nentlungu yesisu ekhawulezileyo, enzima okanye igazi eliphuma esitulweni. Funa ingcebiso kagqirha ngokukhawuleza.
- Ukutya okunempilo, ukuzilolonga rhoqo, ukuphepha ukutshaya, kunye nokulawula izifo ezifana nesifo seswekile kunye noxinzelelo lwegazi oluphezulu kunokugcina lo mthambo kunye nomzimba wonke uphilile.
